Section 728.148Â Universal
Treatment Standards
Table U, "Universal
Treatment Standards (UTS)", identifies the hazardous constituents, along
with the nonwastewater and wastewater treatment standard levels, that are used
to regulate most prohibited hazardous wastes with numerical limits. For
determining compliance with treatment standards for underlying hazardous
constituents, as defined in Section 728.102(i), these treatment standards may
not be exceeded. Compliance with these treatment standards is measured by an analysis
of grab samples, unless otherwise noted in Table U.
